ABSTRACT:
A field emission display (400) includes a cathode plate (410), an anode plate (430), and a mechanical support/getter assembly (300) being disposed between the cathode plate (410) and the anode plate (430). The mechanical support/getter assembly (300) includes a unitary spacer-frame assembly (310) made from a photosensitive glass. A method for fabricating the mechanical support/getter assembly (300) includes the steps of: selectively exposing inter-spacer regions (110) and a getter frame region (120) of a layer (100) of the photosensitive glass to UV radiation, heating the layer (100) to crystallize the UV-exposed regions, and removing the crystallized inter-spacer regions (110) and partially removing the crystallized getter frame regions by contacting the layer (100) with an acid, thereby forming spacer ribs (314) and a getter land (322). The method further includes providing a getter frame (320) on the spacer land (322).
